The NPRM published in the Federal Register on May 11, 2021 86 FR 25810.
The NPRM was prompted by a report that repetitive disconnection and reconnection of certain Ni-Cd batteries during airplane parking or storage could lead to a reduction in capacity of those batteries. The NPRM proposed to require replacing certain Ni-Cd batteries with serviceable Ni-Cd batteries, or maintaining the electrical storage capacity of those Ni-Cd batteries during airplane storage or parking, as specified in EASA 20200274.
The FAA is issuing this AD to address reduced capacity of certain Ni-Cd batteries, which could lead to reduced battery endurance performance and possibly result in failure to supply the minimum essential electrical power during abnormal or emergency conditions. See the MCAI for additional background information.
Discussion of Final Airworthiness Directive Comments The FAA received comments from the Air Line Pilots Association, International ALPA who supported the NPRM without change.
The FAA received additional comments from one commenter, Delta Air Lines. The following presents the comments received on the NPRM and the FAAs response to each comment.
Request for Clarification on the Method of Compliance Delta Air Lines stated that it included the procedures for on-wing preservation of the batteries specified in the service information into its maintenance program work cards. Paragraph 5.2 of the service information referenced in EASA AD 20200274 describes the onwing preservation procedure and the procedures are detailed in Appendix 2
of the referenced service information.
Delta Air Lines noted that the procedure was not directly marked as Required for Compliance RC in either paragraph 5.2
or Appendix 2, but is referenced in another paragraph marked as RC.
Delta Air Lines asked that the AD clarify the method of compliance with the preservation procedures, specifically, if incorporation of the procedures into routine maintenance program work cards is acceptable for AD compliance.
The FAA agrees that the incorporation of the procedures into routine maintenance program work cards does meet the intent of the AD and is, therefore, an acceptable means of
